In reality, tabs is a really arbitrary way of measuring fuel quantity. I've noticed in most Archers, that the very bottom of the tabs is 34 gallons. Most fuelers at least cover the tabs and this puts it over 34 gallons. Most of the time when people call for a top off on an Archer that is already at at tabs, it only takes 10-11 gallons, when in reality it should take 16 gallons.
I think the point is that you know you have at least a certain amount. An extra 5-10 gallons ain't gonna hurt anything.
